For years I have been recording brush strokes as actions and playing them back (so I can record them with a 3rd party screencapture) but all of a sudden, Photoshop will no longer play back brush stroke animations. The brush strokes simply "pop on". Yes, I have "Allow Tool Recording" selected. If I switch playback options to Step-by-Step, the brush strokes pop on one by one but they will not animate. I know the brush strokes are recording correctly, because they still dynamically change if I change brushes. And about the correct amount of time ticks by on an empty screen before the completed strokes pop on.
I've tried resetting preferences, updating drivers, to no avail. I'd think this is just a bug in the latest update but I haven't seen anyone else report this problem... any ideas?
